1653 - Minimum Deletions to Make String Balanced\. Medium You are given a string `s` consisting only of characters `'a'` and `'b'`. You can delete any number of characters in `s` to make `s` **balanced**. `s` is **balanced** if there is no pair of indices `(i,j)` such that `i < j` and `s[i] = 'b'` and `s[j]= 'a'`. Return _the **minimum** number of deletions needed to make_ `s` _**balanced**_. **Example 1:** **Input:** s = "aababbab" **Output:** 2 **Explanation:** You can either: Delete the characters at 0-indexed positions 2 and 6 ("aababbab" -> "aaabbb"), or Delete the characters at 0-indexed positions 3 and 6 ("aababbab" -> "aabbbb"). **Example 2:** **Input:** s = "bbaaaaabb" **Output:** 2 **Explanation:** The only solution is to delete the first two characters. **Constraints:** * 1 <= s.length <= 105 * `s[i]` is `'a'` or `'b'`.
